AI Technical Summary
Existing mining monorail vehicles are prone to exceeding height and width limits during operation due to non-standard materials or improper operation, leading to equipment damage and personnel injury. Furthermore, existing pressure sensors are easily damaged, causing alarm failure.
Design a height and width limit alarm device for mining single-rail vehicles. The device uses a servo motor to drive a threaded rod to move a sliding plate and an infrared sensor. The vehicle size is detected by the height and width infrared sensors, and the alarm emits voice prompts and traffic light signals. The servo motor controls the height of the height limit beam to prevent accidents.
It enables real-time detection of vehicle height and width, preventing accidents from escalating, ensuring safety, and features a durable structure requiring minimal maintenance and easy installation and disassembly.
